Find the producers' surplus at a price level of p = $65 for the price-supply equation below. p = S(x) =25 + 0.1x + 0.003x2 The quantity supplied at the price p is x = (Round to the nearest whole number as needed.) The producers' surplus is $ (Round to the nearest dollar as needed.)Use a numerical integration command on a graphing calculator to find the indicated probability The mean annual wage for firefighters is $45,000 with a standard deviation of $14,000. Determine the probability that a firefighter makes between $40,000 and $60,000 per year Assume a normal distribution The probability that a firefighter makes between $40,000 and $60,000 per year is (Type an integer or decimal rounded to the nearest hundredth as needed.)
